To all whom it mag concern: e

Be it known that I, Cmnnnon H. Ras- MUssnN, a citizen of a he United States, and

of Polk and State ofIowa, have'invented a certain new and usefulKnockdownfitructure, of which the following is a specification.

The object of my invention'is to provide a knockdown structure, such forvinstance' as for pop corn stands, which is of simplefdurable and inexpensive construction.

A further object is to provide such a top, which can be readily and easily putjtogether or taken apart, so that it may be transported or stored in a relative small space. a

A further objectis to provide in such a top, certain features'of construction, where;- by the top may bemade strong and rigid and properly supported.

With these and'other objects in view, my invention consists injthe construction, arrangement and combination ofjthe various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying-drawings, in which:

used the reference numeral 10 to indicate generally the frame of apop .jcornstand or In the accompanying I have brace strips 12, shown in detail in upright flange adjacent tothe-wall frame 10 and with an upper horizontal, inwardly, ex-

tending flange, as shown in-[Figure 2. a resident of Valley Junctionf n" the county The knock-down top hereinafter "more fully described is designed to rest upon the upper edge-of the frame 10 and upon the horizontal flanges of the angle irons 11, so

that the top may be readily and easily re moved and need not be attached by means of bolt screws or the like. j The knock-down top has a lower rectanguflar'frame, comprising a horizontafstrip113 form ng each side of'theframe and resting on the upper edge of the frame 10. The

strip 13, at each side and end of the lower frame of the top member, has at its inner edge a downwardly extending flange let,

which extends downwardly inside the horif "zontal flange of the adjacent angle iron 11,

as illustrated for instance in Figure 2, and

holdsthetop from sliding movement in any direction.

At the outer edgeof each strip portion 13 is a vertical upward extension 15.

At the ends and back of the top, there are formed upwardly opening channels, comchannel members 16 "bent down prising wardly from the upper edge of the members 15 and folded againstthe members 15, as shown in Figure 5. I

At the lower end of each portion 16 is a channel bottom'lf at the inner edge of which is an upwardly extending channel wall 18.

-Thematerial'is bent downwardly at the upper edge of the wall '18 forming an inner member 19 parallel with the wall 18' and serving to support and brace-said wall.

' At the front of the top are'formed two channels like that just described. The front channel is the same as that already described, comprising the members 16,17 and 18. i The member 19 atthe front of the top forms the outside wall of the second or inner channel, which has the bottom 20 and the inner wall 21.

At the upper edge of the wall 21 the material' s aga n bent 'downwardlyas at 22,

forming a port on, which projectsdownwardly below .thechannels and is designed to. substantially rest onflthe strip 13 for. forming a proper support for the channels. The channels ,hereinb efore described serve toreceive thelower edges of panes of glass,

which forms the side and end walls of the removable knockdown top. I I

each corner of my improved top is an upright angle iron post 23. The edges of the flanges of the angle iron post 23 are in each case folded as at 24, (see Figure 4) to form channels.

A brace member is provided in connection with each post 23, comprising an angle iron member 25, shown for instance in section in Figure 4. Spaced inwardly from the post 23, as illustrated, and at the ends of its flanges 24, are extensions 26 and 27 respectively, which are inclined outwardly to the post member 23.

At the ends of the inclined portions 26 and 27 are portions 28 and 29, which are projected into and receive the channels formed between the flanges of the post 23 and the portions 24.

The ends of the members 18 and 19 telminate short of the corners of the knock down top, as shown for instance in Figure 4. The members and 16 extend to the corners beyond the ends of the members 13 and 19.

The portions 26 and 27 and 28 and 29 are cut away at the lower ends of the corner posts and terminate short of the lower ends of the posts 23. The portions 24 of the post 23 are cut away at their lower ends and ter minate at such points as to rest upon the members 15 and 16 (Fig.

Arranged adjacent to the inner surface of the angle iron post members 25 are angle irons 30, the ends of which project beyond the members 26 and 27, as shown in Figure 4 and overlap the ends of the members 19 and 18.

It will, of course, be understood that at porting shelves, there being one such shelf at each corner.

At the upper part of the top. there is pro vided a rectangular frame comprising angle iron members, each having a horizontal flange 34 and an outer downwardly extending flange 35. The flanges 35 are cut away at proper places to permit the flanges 34 to rest on the shelf members 33, as indicated for instance in Figures 2, 6 and 7. The flanges 34 may be secured to the shelf members-33 by means of screw. bolts 36, as shownin Figure 7 and atthe ends of the flanges 34, there may be provided down-turned portions 38, as shown in Figure 7, received between the members 30 and 25, at the upper ends of the latter.

Spaced just outwardly from the flange 35 at the back and ends of the knock-down top are guide strips 39, the ends of which are bent or folded over on the inner sides of the strips 39, as illustrated at 40 in Figure 8. The bent over portions 40 are so arranged that the strips 39 are thus spaced from the flanges 35 to permit a' space into which the panes of glass 41 may be inserted. The portions 40 may be soldered or otherwise secured to the upper frame member, having the flanges 34 and 35.

. At the front of the top, there is formed at the lower part of the flange 35, the spaced, parallel downwardly, opening channels 43 and 44, similar to the channels hereinbefore described. At the inner side of the channel 44 is'a brace member 45, extending upwardly and abutting against the flange 34, all as illustrated in Figure 2.

It will thus be seen that there are provided near the lower part of the front of the knock-down top, two upwardly opening channels, and near the upper part of said top at the front thereof, two corresponding downwardly, opening channels. Mounted in these two pairs of channels are sliding panes of glass 46 and 47, each being a little longer than half the length of the knockdown top.

These panes of glass 46 and 47 may be slid for opening the top to permit access to the interior thereof.

There is provided a cover for my knockdown top, comprising a top member 48, having the ornamental corner posts 49 and provided withthe exterior annular downwardly extending flange 50.

I The cover may have a central ornamental post or rentilator 51.

In the assembling of my knocledown cover, the frame, comprising the members 13 and 14, is assembled and fastened together, and the corner-posts are then bolted to such frame. The glass members 46 and 47 are then placed in the lower receiving channel therefor and the upper frame, having the members 35 and 34, is then placed in position resting on the shelf members 33 and with the upper edges of the glass panes 46 and 47 received in the upper receiving channels therefor.

The bolts 36 are then placed in position. The glass panes 41 may then he slipped in from above between theflanges 35 and the members 39 until their lower edges are received between the members 16 and 18.

The cover member may then be placed in position and the device is completed. I

It is to be noted that at the front of the device, there are two panes of glass, as shown in Figures 1 and 2, which are slidable in 7 panels above and below to substantially overlap for their entire width to permit access to the inside of the top, and which may be readily slid to position, where they only slightly overlap, as in Figure 1.

At the back and sides of the device, respectively, I provide only one pane of glass. In each instance, the lower edge of the side or back pane is received in a suitable panel, while the upper edge isreceived between the flange 35 and the spaced strip 39.

By following these operations in the inverse order the top may be taken apart and packed in small space for storage or transportation.
